Introduction Sepsis is a serious condition where unregulated systemic inflammation can cause organ failure and death. Recent evidence has also shown that sepsis can cause cognitive impairment in surviving patients. However, the mechanisms that cause sepsis-related damage to the brain are challenging to study with the current in vitro tools. In this project, our goal…
Introduction My previous post focused on attempts to reproducibly generate collagen IV with human umbilical vein endothelial cells (HUVECs) so that we would be able to establish protocols for basement membrane protein detection and degradation measurement. Following my presentation on November 18 2020, there were some questions regarding whether or not the observed collagen IV…
Introduction Selective leukocyte interactions with endothelial barriers are a characteristic component of the inflammatory response process. These spatio-temporal interactions can mechanically remodel local tissue, as well as damage healthy tissue with robust inflammation stemming from an over-reactive immune response. This is evident in many pathologies and can complicate severe conditions such as sepsis. Thus, it…
Introduction Breakdown of the blood-brain barrier (BBB) is one of the earliest signs of sepsis and is linked with long-term cognitive impairment. As animal models poorly recapitulate human sepsis, alternative approaches are direly needed to understand sepsis-associated brain injury and develop strategies that protect against cognitive decline. To fill this gap, we are developing a…

Introduction As discussed in a previous post, we are working to adapt a PDMS flow insert as a manufacturable component. While our priority was maintaining the original flow channel geometry as Mansouri et al. designed, we slightly changed the channel length (5 mm –> 4.6 mm) to accommodate an extra bonding area for the pressure-sensitive…
